To LL WHOMIT MAY concnnm Be it known that LC nAnLns Bonmrrsn, of Fitchhnrg, in theconoty of Worcester; and State or? Morse-r V chusetts, hue-invented an Improved DrillingMnehine Ger-rings; 'endil do hereby d'eclarelthnt: the following, taken in connection with the drawings which eccompsny endform part ofthis speeili cetion is c description of myinven'tion suflicient' to enable those-lhilled-in the art to practice it. u My invention relates to the construction and arrangement of parts of roch-drillingmnchine. carriages, designed for supporting a seriesof drilling-machines in drilling for blasting in thnnelegtmines, or qnnrrieni My invention has particular reference to the arrangement of the croesbhrs which cerry gr th ef severcl series organgs of.dril1ing-machines; (and particularly the'bsr which carries theloweri-drillw nhdetotheconltrncr, tion of the framework .of 'the oerr-iage withreferqnc'e to the remonlofi the rock thrown so hxthe-hln ty with referenceto allowing the drill-carriege to he cd vienced torerhthe delirisl np to the breast; sens invent-ism consists primarily in I so monntin g the-lower drilling-machines that they-mnyhe eleyeted etfthd'front of carriage, endin so constructing the cerricgevfrnmeithet cars ey b en npthrongh-itftothe fees of the rock for the remov'el'of the blasted rock, and; so that the cerria ge can he run tip to. the breast,- essoonptthe trcc ks only? are cleared of debris-1f The driwings'tepresent {drilling-machine carri s'ge'embodying my improiemc ts A showse eide'elevetioniB a plan; and C an end elevation of the machine.

a denotes a strong :frame, mo'1inted hn .wheels 6, their-nine end wheels mrehi n gnp-htonjrringe forsnpporting a suitable 'numherqof drilling-machines, c, which mechines' are more immediately mounted in a motel {remework, d,forming 'the, front end of the 'eerri'sge,,tho framework d being composed ofjtwo' rerti cnlways'or reils; e, connected to the carriage-frame a by horiaonte li her s'fi On the rails c are boxes,- g, through was and of 'adjustment, by loosening end tightening the bolt nuts. Each pair of= hoxes'yonithe opposite rsils snpports-e. cross-her, ls; upon which is mounted t ny desirablenumber of drilling-mechines p, eech drill lacing immediately-mounted upon a clamp, l, ghich turns-spun this has to give the-drill isnfdepirghlpjnclinntion in;

.verticsl plane, end the drill-being also so epplied to the clamp has toadmit of Being i nclihed-lstercllj nswell" as vertically, each drill-clamp, 1,. also sliding on the hex-53nd edmitting of being-confined it! shy position nilon'g the length thereof. 4 f I p A-roiindor .a square or other prismatic bar, 1:, ey beemploy'ed tohold: the clamp, snitsble gihe. being interposedbetween the clampcnd the bar (wheneroundf-har. is" not 'j'sed) for the clempto turn np'on in e. Yet ticel pleue, the outer surface of the gibs being mrcde cy'lindric'nli By making the drill-supporting bore ndjn mu s-u height, csshown, th'e drills on any her msy he bronght to the best position iopposite to-the rock surfsce tohe-drilled, this capabilityofwerticcledjhstment and the provision for adjnstin'entJaterally of the drill, and for inclining it in any direction, making it perfectly pr 1 ticnble to reach all points of the heading without moving thevcarriagc, except in a rammdirection, as thework progresses. v r

New, in order to remove the lower drill-her, sons to allow theloo'sened h-ndbroken rock to hethrown under the carriage, and to. allow a car to heron up to the heedingi'l hcng this bar frouhshenfism, by cords or chains at, running hack-to a windless-shet't, o and when the rock thrown down lay-the hlsstis to'beremovegthe bolts of the lower drill-hair boxes are loosened, and the bar is 'drawn up high enough -to allow a car to 'pass freely imdcr the-bsr,ithe elevation of the her also permitting the carriage to be advanced "and the upper drill tobe put at work while the loose 'rock is being thrown down and clcered away.

To allow the car to be runup through the carriage, without disturbing the carriage, I place ail them-ossbeams,p,in the upper part ot'ithe frame, as seen at O, leaving a' clear passage directly through the whole length of the earrings, from side'to sideyof size sutficient to permit a car to be run through the carriage with its load of loose rock. l

This construction greatly facilitstes the sdvshce" intothe rock, as it econoniizes all the time otherwise employed in withdrawing the drillcarriage toallow the, cars to enter. 7

It will be seen that-with a carriage of this description, the entire breast of a tunnel or of n'cu-ttingmay be forked instead of being confined to, w orking d mers lower'isection, and the vcarri'ag'e' also afi'ords facilities as n l staging to accommodate vorkmen engaged in trimming n' ainor projections of rock, and other stagings may be secured to the carriage; o .7

Iclaim thearrangement of one or of a series of horizontal drill-machine belts or holders, substantially as described, so that any of the bars or holders, and especisllj the-lower one or the lower series, maybe elevated tohallow the passage of the carrizige to the bre'astwhen theirack-rail's'onlysre cleared from debris, and to allow passage of a car through the carriage and under the lower bar or bars up to 'the breast.

' Ifalso claim a drill-machine carriage, soconstrncted that a. car may be rlin' up through the carriage, snbs'tantially as set forth. w V V r I CHARLES BURLEIGH,
